Is a bladder at depth similar to a pond at height? Asking for a friend.

Was talking with some friends today about engines, turbos, air tanks, etc. when I came to the conclusion that I would really like an air density update. This update could include the following -O2 Bottle -Fluid connection on seats (to connect to O2 bottle) -turbochargers (Powered by engine exhaust, spool up time, less output) -superchargers (powered by engine power, fuel efficiency hit, instant power, more power) -BASIC altitude/air density (-10% per 1000ft for example)
Basically as you go higher in altitude you would need some specialist equipment to deal with the thinner air for yourself and your engines as well as giving some performance boosts on the ground.
Additionally, does anyone have the discord invite link handy?
So in my class (Commercial ground school) there are still a couple students who struggle to understand how the altimeter wont match up to your actual altitude if the altimeter setting is unchanged. The question is... "An airplane is located at an airport with an elevation of 5000ft msl and a temp of 90f. The altimeter is set to airport elevation. Later that night the temperature plummets to 50f. Unless the altimeter setting is changed, it will read... A. 4800 B. 5000 C. 5200" The answer is 5200ft. Whats the easiest way to explain this. Me and a few other students tried to explain it in multiple ways, but the other students are still slightly confused. What is a good way of explaining it?
I understand that most air is less dense than dry air. But why?
We add something extra, and that causes the density to drop?
Hey guys,
I'm trying to characterize air, using a pressure transducer and hygrometer to find air density. I know there is an obvious qualitative relationship between these parameters, but I'm having trouble locating property tables that have pressure/RH/density, and thought I might see if anyone knows of a quantitative approach I could use.
My plan was to put property tables/the psychrometric chart into excel, then use sensor outputs and labview to locate the density value in excel (using ActiveX), but I'm hitting a wall. It would be tons easier to just have an equation rho(RH, P), which I could simply input in labview.
Thoughts?
Remembering early college physics the reasons is that it causes the projectile to tumble. Which breaks the jet of a shaped charge warhead or shatters a kinetic energy penetrator. I need to know the reasons why the tumbling happens.
The differing densities cause acceleration and deceleration. Right? a=F/DV. Presuming volume remains constant.
But E=DVv2/2. So reduced density should expend less energy.
Didn't post flair earlier, reposted with it.
Pretty much title. encountering big clutters of monsters in a room and blowing them up is a lot of fun but more often then not you come across these small 3-5 mob "packs" that just feel kinda shitty to mow down. and you cant afford to skip them either because you run the risk of not having enough progress when you encounter the end of the map and having to backtrack all the way back to these little mobpacks which is infuriatingly boring.
I think mapping would be a LOT more fun if we can focus on big mobpacks cuz pulling 20 mobs together and AoEing them down is fun. having to stop by at every small pack aint.
